Orr was sentenced to 16 months in prison and Nieta received a 16 month jail sentence suspended for two years.

In the early hours of Saturday 23 December, emergency services responded to reports that a number of people had been injured in Walker Street, in the Wicker area of Sheffield.

Five men were found to be injured, suffering suspected stab wounds and serious injuries consistent with being assaulted.

Investigating officer Detective Constable Katie Clogan said: “All five of the victims in this case had been out celebrating the festive season. Their nights were changed forever as a result of this group’s violent criminality and I hope today’s hearing offers each victim some closure after what must have been a very difficult and traumatic period.

“Our investigation revealed that prior to the victims being assaulted on Walker Street, there had been a pre-cursor incident inside Niche nightclub, which is in the immediate vicinity.

“From CCTV footage, at around 4.30am that morning it became clear that some sort of disturbance broke out in the club, with one man appearing to be assaulted by a group. This led to many people leaving the club, including the victims.

“What followed was unprovoked and incredibly violent – with several of the victims being treated for serious stab wounds.

“I am pleased that the individuals sentenced accepted their role in this serious crime and entered guilty pleas earlier this year, such was the amount of evidence gathered and put before them.

“Four men now face time behind bars for their crime and a number of dangerous individuals are off the city’s streets.”

Sheffield’s Detective Superintendent Una Jennings, force lead for armed criminality, added: “This has been a complex inquiry for officers in Sheffield and as a result of their professional and thorough investigation, several violent and dangerous criminals are now in prison.

“Those affected by this crime were out enjoying the Christmas season, a time for joy and happiness for many across the region, which makes the actions of these criminals even harder to understand.

“Strangers were violently attacked, some suffering potentially life-changing injuries, for no reason whatsoever and this type of disregard for public safety absolutely will not be tolerated by South Yorkshire Police.

“We do not want armed criminality on our streets, we do not want anyone arming themselves for a ‘night out’.

“We want Sheffield to be a safe place for all and will robustly and swiftly respond to any reports of individuals arming themselves or engaging in acts of violence.”
